修改弧线箭头的颜色

该代码来自@marmot 的回复：修改 arcarrow

\documentclass[tikz,border=10pt]{standalone}
\usetikzlibrary{decorations.text}
\definecolor{mygray}{RGB}{208,208,208}
\definecolor{mymagenta}{RGB}{226,0,116}
\newcommand*{\mytextstyle}{\sffamily\Large\bfseries\color{black!85}}
\begin{document}
\begin{tikzpicture}
   \fill[mymagenta] circle (1.35);
   \node at (0,0) [
      font  = \mytextstyle,
      color = white,
      align = center
   ]{
      PDCA\\
      Cycle
   };
   \pgfmathsetmacro{\mydist}{2}
   \pgfmathsetmacro{\Radius}{2}
    \foreach \X [count=\Y] in {PLAN,DO,CHECK,ACT}
    {\pgfmathtruncatemacro{\itest}{sign(sin(180-\mydist-90*\Y))}
    \ifnum\itest>0
    \draw[mygray,line width=1cm,postaction={decoration = {
         text along path,
         text = {|\mytextstyle|\X},
         text align = {align = center},
         raise = -1.0ex
      },
      decorate}] (180-\mydist-90*\Y:\Radius) arc(180-\mydist-90*\Y:90+\mydist-90*\Y:\Radius);
    \else
    \draw[mygray,line width=1cm,postaction={decoration = {
         text along path,
         text = {|\mytextstyle|\X},
         text align = {align = center},
         raise = -1.0ex
      },
      decorate}] (90+\mydist-90*\Y:\Radius) arc(90+\mydist-90*\Y:180-\mydist-90*\Y:\Radius);
    \fi  
      } 
\end{tikzpicture}
\end{document}

是否可以为每个弧形箭头对象设置不同的颜色？非常感谢。

答案1

颜色来自 draw 命令，特别是 colour 的使用mygray。您需要做的就是更改它们。例如，您可以通过向循环添加颜色来为每个颜色使用不同的颜色\foreach：

以下是 marmot 的漂亮代码的更新：

\documentclass[tikz,border=10pt]{standalone}
\usetikzlibrary{decorations.text}
\definecolor{mygray}{RGB}{208,208,208}
\definecolor{mymagenta}{RGB}{226,0,116}
\newcommand*{\mytextstyle}{\sffamily\Large\bfseries\color{black!85}}
\begin{document}
\begin{tikzpicture}
   \fill[mymagenta] circle (1.35);
   \node at (0,0) [
      font  = \mytextstyle,
      color = white,
      align = center
   ]{
      PDCA\\
      Cycle
   };
   \pgfmathsetmacro{\mydist}{2}
   \pgfmathsetmacro{\Radius}{2}
    \foreach \X/\col [count=\Y] in {PLAN/blue!10,DO/red!10,CHECK/green!10,ACT/orange!10}
    {\pgfmathtruncatemacro{\itest}{sign(sin(180-\mydist-90*\Y))}
    \ifnum\itest>0
    \draw[\col,line width=1cm,postaction={decoration = {
         text along path,
         text = {|\mytextstyle|\X},
         text align = {align = center},
         raise = -1.0ex
      },
      decorate}] (180-\mydist-90*\Y:\Radius) arc(180-\mydist-90*\Y:90+\mydist-90*\Y:\Radius);
    \else
    \draw[\col,line width=1cm,postaction={decoration = {
         text along path,
         text = {|\mytextstyle|\X},
         text align = {align = center},
         raise = -1.0ex
      },
      decorate}] (90+\mydist-90*\Y:\Radius) arc(90+\mydist-90*\Y:180-\mydist-90*\Y:\Radius);
    \fi
      }
\end{tikzpicture}
